Blood Test Prep?

I posted earlier that I suspect my 17 month old son has celiac and I was going to just take him off gluten and wait to have him tested. But a friend of mine really recommends that I do the screening. He hasn't had gluten for two days (as far as I know), but I know the test shows up negative if they haven't been eating it. Do you know how long it takes for the antibodies to leave after being off gluten? Or how long he should eat it before I have him tested? I just don't want to get a false negative so I'm wondering if I should test him in the next few days or put him back on gluten first. (I hate to put him back on it thinking about what it is doing to him)!

A few days is not enough to skew the bloodwork, but children are notoriously fast healers. Leaving gluten out of ones diet for one week can cause enough change to be visible on the biopsy. I would put him back on gluten until the testing is complete to your satisfaction (bloodwork and/or biopsy). If you want to go ahead with testing, do it without delay and keep feeding him gluten. Please make sure they run the full celiac panel.

Hope this helps.

      Isolated DPG-Iga

      By trents · Posted

      So, I contacted Scott Adams, the author of that article and also the creator/admin of this website, and pointed out to him the need to clarify the information in the paragraph in question. He has now updated the paragraph and it is clear that the DGP-IGA does serve the purpose of circumventing the false negatives that IGA deficiencies can generate in the tTG-IGA antibody test.

      Lymph nodes

      By Soleihey · Posted

      Has anyone experimenced enlarged lymph nodes with celiac? Both in the neck and groin area. Imaging of both areas have said that lymph nodes are reactive in nature. However, they have been present for months and just wondering how long this may take to go down. Been gluten-free for about two months. Blood counts are normal.

      Hmm interesting I just assumed that any “IGA” tests including the DPG iga would be negative in a person who is IGA deficient but maybe that is not the case for the DPG test.

      If you were just diagnosed I can say that if you go 100% gluten-free should should see dramatic improvement of your symptoms over the next few months, but the hard part is to stay gluten-free. This article has some detailed information on how to be 100% gluten-free, so it may be helpful (be sure to also read the comments section.):
